Pakistan’s EEZ is enormously rich; both in living and non-living resources. Efforts are in hand at various levels to explore, exploit and benefit from these resources. It is PMSA’s one of the primary responsibilities to protect these resources against unauthorized exploitation by other countries. For this purpose, aircraft and corvettes of PMSA are extensively used to carry out patrolling and surveillance of EEZ. Prior to the establishment of PMSA, fishing boats and trawlers of neighbouring countries had been involved in illegal fishing on a large scale in the region adjacent to Indus delta, causing a huge loss to national exchequer. PMSA, since inception, has been striving hard to keep this zone under effective surveillance to ensure protection of our resources. PMSA has been successful in curbing these illegal fishing activities to a large extent.
